945,529. specification o! um:- rmnt Patented J an. 4, 1910. Application filed larch 15, lacs. Serial No. 486,280.

To all whom it may concern: hood since if the Be it known that I, Wmuau S. Ilnswsmi, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Im rovements in OrchardHeaters; and I do eclare the following tohe a full, clear, and exact dcscri 'on of the invention, such as will enable ers skilled in the art to which it appertains to make and use the same referencebeing had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in orchard heaters.

My improved device is adapted for use to prevent injury by frost to vegetation in various sections 0 the country, being more especial] adapted for use in horticultural regions or the protection of fruit of various kinds from in by late frosts in the spring and early in the fall.

My improved device is adapted for use 1n burning lipid fuel as Oll, the fuel receptacle in the pre rred size of the device having a capacity ada ted to burn four or five hours, or the peri (generall during the night), when a heater of this 0 aracter is reqn In using my improved device, the mdividual heaters are distributed at suitable intervals over the territory to be protected, and arranged in such proximity1 to each other as to raise the tem ature t roughout the entire area, sufiicien y to prevent. injury from the aforesaid cause.

M object is to provide a. device which she be exceedingly simple and, therefore of economical construction, and which shall at the some time elliciently rform the function of protecting orchnr s and other vegetation from injury due to the said cause.

Specifically, the invention consists of a simple fuel receptacle, to the to 1 of which is rcmovubly applied a hood of rusto-couicnl sha e, its base having the greatest diameter on of such size as to fit over the top of the fuel receptacle, and maintain its position thereon.

In the preferred form of construction, the hood is provided with u number of orifices permitting the entrance of air to facilitate combustion. The upper part of the fuel rccupl-uclc, however, may he pcrforutcd while the hood is plain or impcr orute, if desired. It is preferred to make the apertures iu the are formed in the to of the fuel recepta e, they lessen the fueFcapacity of the latter.

Having briefly outlined m im rovcd construction, I will proceed to escn the same in detail, drleiereuce bein nlilade the 11:30:11-

anyl wing in w ic isi ustrat an mhod i nent thereof.

In this drawing, Figure 1 is a side elevation of my improved orchard heater. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a perspective detail view of the hood. Fig. 4 is a section similar to Fig. 2, showing a slightly modified form of construction. Fi 5 is an elevation illustrating still another: mm of construction showing the hood tilted for draft regulating purposes. F' 6 is a view looking at Fig. 5 in the direction of arrow 6, the hood, however, bein shown in vertical section.

T 1e same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the body portion or fuel recc tacle o my improved orchard heater. is receptacle as shown in the drawing is frusto-conical in shape, its smaller extremity hein lowermost; This receptacle is adapted to old a suitable quantity of lirauid fuel 6, it being my intention to use cru e petroleum for this pur so.

To the to of the fuel rece tac e, is applied a he 7 which is also sto-conicul in shape, its lower extremity, however, being largest. This hood has its larger extremity lowermost where the hood is formed of sliglhtly larger diameter than the top of the fue receptacle, whereby the hood is adapted to project a short distance below the top of the rose tncle as shown at 8. The hood is equippe with 11 number of orifices 9 for the entrance of air to facilitate combustion. The function of the hood, is to provide the necessary draft for combustion purposes and this fuucl ion is enhanced b the special con struction or shape of the mod whereby its diameter diminishes in size from the bottom to the top of the hood.

In the form of coustrucllou shown in Fig. 4, the hood is plain or impcrfornlc, while the u )pcr portion of the fuel rcccpluclc is provh ed with omuiugs 10 for the rulruucc of air for com usliou uu' noses. in this ruse, the hood porl'oruml m uuctiou of proaluciug the required dru it while lhu ori ices l0 udmil the necessary uir for plll'llhstfl of umnbustiun. As heretofore slulcrl, however,

it is preferred to form the air orifices in the hood since they ierform the required func tion, without diminishing the capacity of the fuel receptacle.

In the construction shown in Figs. 5 and G, the bottom of the hood 7 normally projects below the to of the receptacle somewhat further than 1n the construction shown in the other views, thus makin it racticahle to tilt the hood to a eonsi erab e degree as shown in Figs. 5 and 6, for draft controlling purposes. It is evident that the tilting of the hood will have a tendency to check the draft by changing the direction of the air current. Moreover, by tilting the hood as shown in the last named views, the openings 9 on one side of the hood are partly closed a ainst the entrance of air to the hood. '1 iis is important where it is desired to regulate the draft in a device of this character.

Having thus described my invention, what I claim is:

1. An orchard heater comprising a fuel receitacle and an open-ended draft hood tilta ly and removably applied to the top thereof. the upper portion of the device above the fuel havin orifices which may be partly closed when tie hood is in the tilted positlon.

2. A heater of the class described comprising a fuel receptacle open at the top, and an 0 en ended hood tiltably and removabl app ied to the top of the fuel receptacle an having orifices which may be partly closed when the hood is in the tilted position.

3. An orchard heater comprisin a fuel receptacle open at the top and a 00d of l frusto-conical shape, having its larger extremity lowermost, said hood being open at both ends and having its interior entirely unobstructed, leavin a free draft passage, the hood being tiltably and detachably a 1- plied to the top of the fuel receptacle t e l hood having orifices which may be partly closed when it is in the tilted position.

4. An orchard heater comprising a fuel receptacle open at the top, and a draft hood of frusto-conicul shape havin its larger extremity tiltably and removal I applied to the top of the fuel receptacle, t 1e hood having orifices and having its interior entirely unobstructed, leaving a free draft passage, the orifices of the hood being in its lower portion and adapted to be partly closed when the hood is in the tilted position.

5. An orchard heater comprising a frustoconical fuel receptacle having its greatest diameter at the top which is-o en, and a hood of frusto-conical shape aving its larger extremity detuchably applied to the top of the fuel receptacle its interior beino' entirely unobstructed, leaving a free drafi pamge, the hood being open at both ends and provided with Ol'lfiCBS which may be partly closed when the hood is in the tilted position.

6. An orchard heater com rising a fuel receptacle and a draft hood tiltabl applied to the top thereof for draft contro ling purposes, the hood having orifices and its interior being entirely unobstructed leaving a free draft passage, the orifices of the hood b00213; arran ed to be partly closed when the h is in t e tilted position.

7. An orchard heater com rising a fuel receptacle and a draft hood tlltabl applied to the top thereof for draft contro ling purposes, the lower part of the hood having orifices which may be artly closed when the hood is in the tilte position, substantially as described.

In testimon whereof I afiix my signature in presence 0 two witnesses.
